Question

Write down a pair of integers whose (a) sum is –3 (b) difference is –5 (c) difference is 2 (d) sum is 0

Answer 1

Let integers be x and y
(a) x + y = -3
x - y = -5
Use elimination to solve for y (add the two equations)
You should get
2x = -8
Solve for x and then substitute in one of original equations.

Work (b) the same way.
